Abstract: Disclosed are a portable electronic device and an operation method thereof. The portable electronic device comprises a body, a barcode detector and a barcode decoder. In the barcode detector, a first image capturing module continually captures a barcode image when the portable electronic device is operating in the resting mode, a first buffering module temporarily stores the captured barcode image, and a first image processing module processes the stored barcode stored and counts a number of times when the barcode image has a predetermined pattern feature. When the number of times reaches to a threshold number, the barcode decoder is turned on to capture and decode the barcode image, and the barcode detector is switched to operate in a power-saving mode.

Abstract: An object determining system, comprising: a processing circuit; a first stage object sensor, for generating a first stage object sensing result of an object; and a second stage object sensor, for generating a second stage object sensing result of the object if the processing circuit determines the object exists in a predetermined range based on the first stage object sensing result, wherein the processing circuit further determines an object kind of the object based on the second stage object sensing result; a line light source; and an area light source. The first stage object sensor generates the first stage object sensing result based on the line light. The second stage object sensor generates the second object detecting result based on the plane light. The first stage object sensor is a depth sensor or a thermal sensor. The second stage object sensor is an image sensor or a thermal sensor.

Abstract: An optical sensing system is provided. The optical sensing system includes a first light source, a second light source, a light sensor, and a processor. The processor is configured to: control the first light source to scan a horizontal detection area; control the light sensor to capture a first frame by receiving first reflective lights from the horizontal detection area; obtain a first reflection pattern, and analyze the first reflection pattern to determine whether an object is within the first portion; if so, control the second light source to scan a first vertical detection area; control the light sensor to capture a second frame from the first vertical detection area; process the second frame to obtain a second reflection pattern, and analyze the second reflection pattern to determine whether the object is detected by a misjudgment.

Abstract: A sensor device includes an image sensing array, a frame buffer, a first read line, a second read line and an energy accumulator. The image sensing array is configured to sense reflected light from a working surface and includes a plurality of sensing pixels and a plurality of self-powered pixels. The sensing pixels respectively output image data according to the sensed reflected light. The self-powered pixels respectively output photocurrent according to the sensed reflected light. The first read line is coupled between the sensing pixels and the frame buffer. The second read line is coupled between the self-powered pixels and the frame buffer. The energy accumulator stores electrical energy of the photocurrent via a charge path between the self-powered pixels and the energy accumulator.

Abstract: A method for eliminating misjudgment of a reflective light is provided. A light source emits a transverse linear light toward a direction of a floor as detection light and the light sensor senses reflective light signals from an object that reflects the detection light. In the method, a frame image including the reflective light signals is captured by the light sensor, centers of gravity of the reflective light signals are analyzed, and the centers of gravity of the reflective light signals can be corrected based on a line of gravity or a center of gravity of previous reflective light signals stored in a memory of the autonomous robot in order to exclude a center of gravity generated by the reflective light signal from a wall. A distance of the object can be confirmed based on the corrected centers of gravity of reflective light signals.
